Exhibition preview: The Dream Of Fluxus, Gateshead

This is the largest exhibition of Fluxus art ever held in Britain, with over 350 works. Always on the move, formally various, intellectually elusive, theoretically questioning, Fluxus is/was just about impossible to define. Flourishing internationally in the 1960s and 70s, Fluxus represents a series of free-ranging attempts to escape capitalism's stifling appropriation of creativity. Thus - in these days of the bloated art market hitting a financial downturn - this promises to be an immaculately timed show. Centred around the work of the ironically self-appointed "chairman of Fluxus", George Maciunas, The Dream Of Fluxus charts the influence of, among others, the radical composers John Cage and Karlheinz Stockhausen on a generation for whom art seemed more about living spirit than collectable stuff.
